Got KitKat and miss an old Android OS like Gingerbread? Then use ADW to recreate it.

No. 3: Action Launcher

Action Launcher claims 100,000 to 500,000 installs and has an average Google Play Store rating of 4.3 stars out of a possible 5 from 9,159 reviewers. Requires Android 4.0.3 and up.

Chris Lacy's Action Launcher is nipping at the heels of big dogs Nova and ADW with some innovative interactions. They include a way to create and launch widgets by swiping at an app's icon.

Quickage lets you launch a Home page from the right edge of the screen; Covers is an advanced form of folder that lets you group icons; and Shutters lets you group widgets on the home screen.

No. 4: Apex Launcher

Apex Launcher claims 5,000,000 to 10,000,000 installs and has an average Google Play Store rating of 4.4 stars out of a possible five from 94,962 reviewers. Requires Android 4.0.3 and up.

Another major Launcher, this skin provides elastic scrolling and a lockable desktop to prevent changes.

Transition effects, multiple drawer styles, and an advanced theme engine with icon packs and skins from third-party developers, including a copy of the much-loved HTC Sense UI, round out the mix.

No. 5: Transparent Screen Launcher

Transparent Screen Launcher claims 10,000,000 to 50,000,000 installs and has an average Google Play Store rating of 3.9 stars out of a possible 5 from 33,050 reviewers. Requires Android 2.2 and up.

ForU naveen's Transparent Screen Launcher is a wonderful idea, with an unfortunately misguided execution. The concept is that your home screen becomes transparent, using the device's camera. It's a kind of augmented reality where you can see behind the phone as you're looking at the screen.

The developer pitches it as ideal for pedestrian safety -- you can look at your screen while seeing where you're going.

It does look awesome, and it does make your phone look transparent, but it's full of junky apps -- so be warned if you want to try the experience.
